GAOTek Mini OTDR tester

Description Overview GAOTek mini OTDR tester is a new generation of intelligent optical measuring instrument designed for the optical fiber communication system testing. This product is mainly used to measure the parameters of optical fibers and cables, such as length, loss, and connection quality, etc. it can realize the accurate positioning of event points and fault points, and can be widely used in the construction, maintenance testing and emergency repair of the optical fiber communication systems as well as the research, production and production measurement of optical fibers and cables and so on. This product can provide you with the highest performance of solutions for installation and construction of fiber optic network construction and the subsequent fast and efficient maintenance and troubleshooting testing. It has novel appearance, durable; it has the simplest interface and intuitive operation in the OTDR industry; among the same type of handheld products, its unique dual operation mode of key plus touch screen can greatly simplify the user’s application; with one-key analysis, it can quickly obtain the test results. The events are displayed in the main interface in a way of list, and such information includes event number, type, event location (distance), loss, reflection, event point attenuation, total loss, etc..; the whole machine adopts the intelligent power management mode; the high capacity of lithium battery can make the whole machine working for more than 10 hours, so it is very suitable for outdoor environments for a long time.   Technical Specifications Type Of Optical Fiber Single Mode Fiber Center Wavelength  1310 nm or 1550 nm ± 20 nm Dynamic Range (Db) 30 dB or 29 dB 36 dB or 35 dB 40 dB or 39 dB Event Blind Zone 4.9 ft (1.5 m) 4.9 ft (1.5 m) 4.9 ft (1.5 m) Attenuation Blind Zone 32.8 ft (10 m) 32.8 ft (10 m) 32.8 ft (10 m) Display Type 3.5in, color LCD, touch screen operation Optical Interface FC or UPC (Interchangeable SC, ST) Measurement Range (Db) 0.3 mi, 0.62 mi, 1.2 mi, 2.4 mi, 4.9 mi, 9.9 mi, 19.8 mi, 39.7 mi, 79.5 mi (500 m, 1 km, 2 km, 4 km, 8 km, 16 km, 32 km, 64 km, 128 km) Pulse Width 5 ns, 30 ns, 50 ns, 100 ns, 275 ns, 500 ns, 1000 ns, 5000 ns, 10000 ns Range Accuracy ± (1 m sampling interval 0.005% × distance)  Attenuation Measurement Accuracy   ± 0.05 dB/dB  Reflection Measurement Accuracy ± 4 dB Data Storage ≥ 1000 test curves Communication Interface USB Output Power ≥ 2 mW Test Distance ≥ 3.1 mi (5 km) Power Supply Mode  AC or DC adapter: AC: 100 V to 240 V (1.5 A), 50 Hz or 60 Hz, DC: 12 V ± 0.25 V (2 A) Internal lithium-ion battery pack: 7.4 V, 3200 mAh  Battery Operation Time ≥ 5 hours Operating Temperature 23 ℉ to 122 ℉ (-5 ℃ to 50 ℃) Storage Temperature -4 ℉ to 158 ℉ (-20 ℃ to 70 ℃) Relative Humidity  0 % to 95 %, no condensation Weight ≤ 2.2 lb (≤ 1 kg)
